Subject: fix dma_alloc_coherent on m68knommu / coldfire
Date: Mon, 21 Nov 2022 10:56:29 +0100 [thread overview]
Message-ID: <20221121095631.216209-1-hch@lst.de> (raw)
Hi all,
this series ensures dma_alloc_coherent returns NULL for m68knommu and
coldfire given that these platforms can't actually allocate dma coherent
memory after fixing what is according to an old mail from Greg the
only driver that actually uses memory returned by dma_alloc_coherent on
those platforms.
